Prosecutor, John Reading, told jurors that Jutting subjected Sumarti to ‘increasingly cruel acts of violence using his belt, sex toys, a pair of pliers and his fists’.

‘After torturing her for three days, he took her into the bathroom, had her kneel in front of the toilet bowl with her hands tied behind her back, made her lick the toilet bowl and then he cut her throat with a serrated-edged knife,’ he added.

The court in Hong Kong also heard that the defendant recorded the scenes of torture using his mobile phone.

But Jutting, 31, has denied murdering the two women.
